[CM] Snd and mp arithmetic

[e deleflie]

All,

I've got an SND script that does sample rate conversion (usually from
44100 to 48000) on multichannel files. Code looks something like this:

                        (src-sound (/ (srate insound) 48000) 1.0 insound 0)
                        (src-sound (/ (srate insound) 48000) 1.0 insound 1)
                        (src-sound (/ (srate insound) 48000) 1.0 insound 2)

I'm running this script on Amazons' EC2 (cloud computing
instance)..... and it barfs .... took me a while to work out that SND
is filling up the /tmp/ directory with enough files that it the
computer has no more room to breath. .... looks like this:

-rw-r--r--  1 amber amber  48032520 2009-01-21 18:22 snd_2166_0.snd
-rw-r--r--  1 amber amber  22974464 2009-01-21 18:23 snd_2166_10.snd
-rw-r--r--  1 amber amber  48032520 2009-01-21 18:22 snd_2166_1.snd
-rw-r--r--  1 amber amber  48032520 2009-01-21 18:23 snd_2166_2.snd
-rw-r--r--  1 amber amber  48032520 2009-01-21 18:23 snd_2166_3.snd
-rw-r--r--  1 amber amber 192129992 2009-01-21 18:23 snd_2166_4.snd
-rw-r--r--  1 amber amber  48032520 2009-01-21 18:23 snd_2166_5.snd
-rw-r--r--  1 amber amber  48032520 2009-01-21 18:23 snd_2166_6.snd
-rw-r--r--  1 amber amber  48032520 2009-01-21 18:23 snd_2166_7.snd
-rw-r--r--  1 amber amber  48032520 2009-01-21 18:23 snd_2166_8.snd
-rw-r--r--  1 amber amber  23068712 2009-01-21 18:23 snd_2166_9.snd

I'm wondering if this is because of the re-sampling? Is there anything
I can do about it? ... what is it doing ... is it swap files or
something? Should the files get deleted (if the process was
successful?)
